Specifying the Geometry

This section or topic is specific to Console Mode.

By default a DICTRA module system has a planar geometry. To change the geometry of the system, use ENTER_GEOMETRICAL_EXPONENT followed by a number 0 (planar), 1 (cylindrical) or 2 (spherical).

About Geometry and Coordinates

With a cylindrical or spherical geometry, the system’s zero coordinate (left boundary) is at the centre of the cylinder or sphere. The highest coordinate (right boundary) is defined by the cylinder or sphere radius. If you want a geometry corresponding to a tube or a hollow sphere, then use SET_FIRST_INTERFACE to locate the system’s left boundary at a coordinate that is greater than zero.
